Aleksandyr is bounded by fate and knows it. It’s like the saddest thing of all. The forces of fate are strong and compel everyone to eliminate the Unbound.
I like to theorise that Fuckster was with Aleksandyr for the entire arc because Fuckster was the most precious part of Ryybyn’s soul that was within Aleksandyr’s ability to save from Ragnaxxa’s corruption. Fuckster represents that inherently good part of Ryybyn that just wants to be friends with everyone and make everyone feel loved.
